Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Pressure is a scalar quantity even though it is defined as force divided by area. Reason (R): The force under consideration in the definition of pressure is always perpendicular to the surface area, and no direction can be assigned to pressure independent of the surface orientation. In the light of the above statements, choose the correct answer from the options given below:

1. A
   Both (A) and (R) are true and (R) is the correct explanation of (A).
2. B
   Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. C
   (A) is true but (R) is false.
4. D
   (A) is false but (R) is true.
